Linde Canada to showcase novel latent print development technology

Trade News

Mississauga, Canada, 7 February 2012 - Fingerprint identification, arguably the most common forensic evidence used worldwide, has just taken a significant leap forward with the introduction of a revolutionary automated processing system developed by Linde North America. This dry, non-contact technology uses a gaseous application process for developing latent fingerprints, eliminating hazardous carrier solvents used in traditional processing methods and the physical application of these materials by dipping, spraying, brushing and drying.

Linde will display the ADROIT™ FC 300 latent mark visualization system at booth #720 during the American Academy of Forensic Sciences (AAFS), 64th Annual Scientific Meeting held at the Atlanta Marriott Marquis Hotel in Atlanta, Georgia, February 22-24, 2012. The AAFS annual scientific meeting gathers professionals who present the most current information and research in the fields of forensic science. The conference exhibit showcases the latest technologies and services to forensic science professionals from around the globe, including toxicologists, physicists, engineers, educators and many other disciplines.

A prototype of the Linde system has undergone extensive evaluation by a research team at a major US Forensic Crime Laboratory who will present results of their evaluation at the AAFS criminalistics section Friday, February 24th at 2:45 p.m.

Calvin Knaggs, marketing manager, specialty markets equipment Linde Canada, said, "The new Linde technology is a flexible tool designed with both the forensic investigator and research scientist in mind. It's a dry process, capable of developing latent prints on a wide range of porous and non porous materials including thermal papers. The programmed recipe control lends itself to standardized practices, ensuring precision while eliminating the complexities and potential inaccuracies associated with mixing and applying solvent carriers. This is truly a step change in fingerprint development technology, eliminating many of the storage, safety and environmental problems associated with the current art."

The Linde technology applies detection chemicals by sublimation and dilution in a proprietary carrier gas injected into a low pressure environment. The gas mixture expands, uniformly coating all exposed surfaces (the evidence), thus depositing a thin film which adheres to, or chemically reacts with, the print residue making it visible to the unaided eye or under alternate light source (ALS) or laser excitation.

Linde Canada is a member of The Linde Group, a world-leading gases and engineering company.

The Linde Group employs approximately 50,000 people working in more than 100 countries worldwide. In the 2010 financial year, it achieved sales of EUR 12.9 billion (USD 17.9 billion).
